Abstract

The present invention is a dynamic password system and method based on a mobile communication terminal, which includes a mobile communication terminal and a dynamic password verification server; The password generation time is combined with a symmetric encryption algorithm to generate a dynamic password, and the dynamic password is output; the dynamic password verification server has: a dynamic password verification unit, which is used to obtain the dynamic password and solve the dynamic password from the dynamic password obtained. Password generation time, compare this dynamic password generation time with the current dynamic password verification server system time, if the two times are synchronized, then use the same algorithm as the symmetric encryption algorithm to generate a verification code, if the dynamic password is the same as the verification code If the verification codes are the same, the dynamic password passes the verification. Therefore, the cost problem of the hardware client and the time synchronization problem are solved, and the security of the system is guaranteed.

Description

technical field [0001] The invention relates to a technology combining wireless communication, network communication and password verification, specifically a dynamic password system and method based on a mobile communication terminal. Background technique [0002] With the popularization of Internet applications and more and more application systems running on this public network, at the same time, following the development of science and technology, more and more enterprises are interconnected through public networks, so remote identity confirmation becomes It is extremely important. Although some systems provide complex identity confirmation mechanisms such as certificate authentication, most systems still use the traditional user ID plus password authentication method. There are many problems in this identity verification mechanism, such as: it is easy to guess, intercepted in the middle of transmission, not stored safely, stolen by hackers, or even cheated by fake syste...
